Thanks for the additional info @hdrazo 

There may be a couple different variables in play here. Are you certain this is a network license? A standalone will not have the capability to activate via server. As for the other variable, You mentioned this is on a Mac, as the license is intended for, however, it sounds like you may be running on a parallel? Or perhaps Boot Camp? Could you attach a screenshot of the error you are encountering? 

Please be sure to "whiteout" any personal information contained in the screenshot, like your serial number, and any server information you do not wish to be public.

Thanks!
